I use something really similar to this handout when kids get sick.

I say something along the lines of
"Hey DCM/DCD, here's a really good handout about cleaning and sanitizing at home when your child is sick. I use similar methods here at daycare to keep everyone healthy as possible so I thought it might be useful for parents as well"
Sometimes I simply staple it to the back of the form I use when I send a child home from care.
